Abby wants to use her savings of 1,325 to learn yoga. The total charges to learn yoga include a fixed registration fee of $35 an
NISA [10]

Answer:

Maximum number of months Abby can learn yoga is 25 months.

Step-by-step explanation:

We have given,

Total savings of Abby = $1325

Total charges to learn yoga is given as:

A fixed registration fee = $35

And a monthly fee = $50

Since the registration Abby pays only once. So we can calculate the remaining saving amount for Abby.

i.e Remaining saving amount after registration fee = $ (1325 - 35) = $1290

Now, from the remaining amount after paying registration fee , let the Abby learn yoga for x months.

To find maximum number of months we need to satisfy a equation given as:

x*50 \leq 1290

or x\leq \frac{1290}{50} \\x\leq 25.8

Since we got x ≤ 25.8 months   ≈ 25 months (in integer form)

So maximum number of months Abby can learn yoga is 25 months.

Sam has $2.25 in quarters and dimes, and the total number of coins is 12. How many quarters and how many dimes?
a_sh-v [17]
N₁*$0.10 + n₂*$0.25 = $2.25

n₁ + n₂ = 12

-----------

This means that:

n₁ = 12 - n₂

And:

(12 - n₂)*$0.10 + n₂*$0.25 = $2.25

12*$0.10 - n₂*$0.10 + n₂*$0.25 = $2.25

$1.20 + n₂*$0.05*(5-2) = $2.25

$1.20 + n₂*$0.05*3 = $2.25

$1.20 + n₂*$0.15 = $2.25

n₂*$0.15 = $2.25 - $1.20

n₂*$0.15 = $1.05

n₂ = ($1.05)/($0.15)

n₂ = 7

If n₂ = 7:

n₁ + 7 = 12

Therefore, n₁ = 5.

---------

Answer:

5 dimes and 7 quarters.
